I cant get my engine temp to get up to 90 and it's driving me insane

[BlackLeon]

I cant get my engine temp to get up to 90 and it's driving me insane. I have changed the thermostat, the sensor, the coolant, spark plugs, coilpacks and had it fully serviced reguarly and it still wont budge (I know sparks etc wont be the issue but they needed doing anyway..)

What am I left with? Dodgy maf?

I also have the strong fume smell coming through the vents at a standstill but I cannot find a split ANYWHERE! I doubt this is related?

Help guys please I would really like to get this sorted!

Thanks.

Edit - the temp wont get above a quarter so 75 degrees? and is more likely than not sitting just below that

This may be a long shot but has anyone remove the clock and pulled the needles off before now ?

 

[BlackLeon]

No, not that I'm aware of. I've owned the car for nearly 3 years and it's only been doing this for the last 4-6 months.

Has the car been checked with vag-Com to see what temperatures it's showing?

Maybe your new thermostat was faulty?

Possible your water pump is on the way out (no idea)?

 

[BlackLeon]

Water pump changed with the cambelt 8k ago. I have no access to vag-com annoyingly. When the thermostat was first changed the temp stayed just below 90 but never at the full 12 o'clock. Probably a week later it all went back to how it is now. Is it really possible the new thermostat is failing?! That would be some poor luck!

ar my bad didnt know it has only just started happening defo vag-com check temps

 

[BlackLeon]

Why vag-com though? Is it to rule out whether I just now have a dodgy needle? Surely not?

It would help rule out your gauge.

Had the same problem after putting 2 new thermostats in. If you have already done that it more than likely just needs bleeding. I popped to my local mechanic and he sorted it in 5 minutes

you tried coolant temperature sensor ? the green 1 in your coolant tank at the top

What about using the climate console to dispaly engine coolant temp? I can't post links yet (newbie still) but i found the guide here

[Sinbad]

slightly offtopic, is there something similar to the above for dual-zone climate control or full MFD in a mk2 leon?

 

[BlackLeon]

I've changed the temp sensor twice in the last year. Bleeding? You mean changing the coolant? I did this a month ago when changing the thermostat. You think maybe doing it again? Why would the coolant need replacing if brand new?

 

[Sinbad]

Not changing - bleeding. Perhaps there's an airlock or bubble in the system somewhere, bleeding is the process of removing air.

 

[BlackLeon]

How do I go about doing that, that sounds very possible..

 

[Sinbad]

Have found the following;

Run car from cold, leaving the coolant tank cap off until car gets to temp. if your thermostat works you'll see the coolant level drop, then rise again after a few minutes, that means your thermostat is working. you should notice some coolant flowing from the return line, that means your waterpump is working. massage coolant hoses by hand. the process should take about 15 min. fill it to level, cap it then drive around, check levels again.

I did this and it wasnt doing much,after 30mins of doing it I popped the lid back and with a second person holding the revs at 2.5k rpm i squashed all the hoses to get the air out, was told it needs to be under pressure to remove them if its really stuck-worked like a charm

 

[BlackLeon]

Thanks guys, thats great I'll try that soon and let you know how I get on

 

[CupraRmark]

just a quick question are the fans working correctly i.e not stuck on all the time keeping it a little cooler than normal ??? worth a check m8
